[telmah2]

Hi I have a 92 patrol wagon 4.2 EFI dual fuel and would like to know the in's and out's of puting a turbo on any info would be great.

I know the guys in my sig were keen on doing one but they are in sydney and your not but they may be able to point you in the right direction.

Look around and pick up a highflow t3 (from a Vl) or a T3/T4. get a manifold made up or u can use a diesel one. Get oil lines made up, buy the right sized piping for the intake and turbo outlet, bolt it all together and enjoy.

Does the desel manifold fit straight onto the petrol, does that mean the dump pipe would be the same too?

[Bond]

It does fit straight on but they dont leave much room for the dump pipe. Thats why i'm getting one custom made and its only a little bit more.

Mate you gotta look into whether your injectors will handle the fuel supply needed when you turbo it. Also does the standard computor understand positive manifold pressure. These are the most important things.

standard computer will be be barely fine for low boost applications - you have to run a rising rate fuel pressure regulator to compensate.. just means it'll run rich as **** at idle.

allocate $1500 or so for an aftermarket computer, you'll be much better off this way.

If your going to run petrol then an aftermarket computer is the way to go.

Apparently Nissan GTR injectors are a direct swap.
